ABSTRACT
Objective:To analyze the factors influencing prognosis of intrahepatic cholangiocarcinoma (ICC) after surgical resection.Methods:The clinical data of patients diagnosed with ICC and who underwent surgical resection from December 2015 to December 2019 at the Fifth Medical Center of PLA General Hospital were retrospectively analyzed. Of 39 patients who were included in this study, there were 23 males and 16 females, with age of (54.1±7.2) years old. The body mass index, hepatitis B virus infection status, tumor diameter, degree of differentiation, microvascular tumor thrombus, lymph node metastasis, and serum levels of carbohydrate antigen 19-9 (CA19-9) were analyzed as risk factors affecting postoperative recurrence and survival.Results:The median times to recurrence were significantly better in patients with a tumour length <5 cm (11 vs. 5 months), patients without microvascular tumor thrombus (54 vs. 6 months) and patients without lymph node metastasis (8 vs. 5 months) (all P<0.05). The median survival of patients with CA19-9≥100 U/ml was significantly shorter than that of patients with CA19-9<100 U/ml, (9 vs. 27 months, P<0.05). Tumor diameter>5 cm, microvascular tumor thrombus, lymph node metastasis, and CA19-9 ≥100 U/ml are risk factors affecting the recurrence time after ICC resection, CA19-9 ≥100 U/ml is a risk factor affecting survival time after ICC resection. Conclusion:Tumor diameter, microvascular tumor thrombus, lymph node metastasis and CA19-9 can be used to estimate the risk of ICC recurrence, and CA19-9 level can be used to estimate postoperative survival of ICC patients after resection.
ABSTRACT
Objective:To study the efficacy of direct intrahepatic portosystemic shunt (DIPS) in treatment of Budd-Chiari syndrome (BCS).Methods:From January 1, 2015 to June 31, 2017, consecutive patients with BCS who were treated with DIPS at the Department of Interventional Therapy of Beijing Shijitan Hospital, the Liver Disease Research Center of Beijing Friendship Hospital and the General Surgery Department of Beijing Ditan Hospital were retrospectively analyzed. The symptoms, physical signs (including abdominal distension, ascites, pleural effusion, splenomegaly, hepatic encephalopathy) and perioperative laboratory results of these patients were collected and analyzed. Biochemical indicators including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), direct bilirubin (DBil), and portal pressure gradient were compared before and 2 weeks after treatment. The patients were followed up for at least 3 years to assess their clinical symptoms, patency of shunt, oncological status and survival.Results:Of 67 patients with BCS who were included in the study, there were 45 males and 22 females, aged (38.12±23.22) years. The BCS classification of these patients were hepatic vein type ( n=65), including 62 patients with complete hepatic vein obstruction, 3 patients with hepatic vein occlusion due to thrombosis, and 2 patients with mixed hepatic vein and inferior vena cava occlusion. All 67 patients underwent DIPS with 93 stents being implanted. In addition, 43 patients underwent gastric coronary vein embolization, and 2 patients with mixed type of BCS underwent inferior vena cava stenting. The portal pressure gradient decreased from (22.17±9.16) mmHg (1 mmHg=0.133 kPa) to (9.87±4.75) mmHg, the difference was statistically significant ( P<0.05). Abdominal distension was relieved, at one month and ascites completely subsided in 3 months after operation. The liver congestion and swelling were obviously relieved. Comparison of patients 2 weeks after operation and before operation, ALT decreased from (65.28±27.75) U/L to (28.43±13.46)U/L, AST from (68.75±29.23) U/L to (26.92±13.33)U/L, TBil from (175.31±80.48)μmol/L to (45.08±26.54)μmol/L, DBil from (127.55±44.65)μmol/L to (35.12±10.77)μmol/L, and albumin increased from (31.56±7.22) g/L to (44.18±11.36)g/L, the difference was statistically significant (all P<0.05). All patients were followed up for at least 3 years. Shunt stenosis was detected in 5 patients (7.46%) with shunt expansion being performed, variceal bleeding in 2 patients (2.99%), ascites recurrence in 4 patients (5.97%) and hepatic encephalopathy in 2 patients (2.99%). No patients were diagnosed with hepatic cancer, and no patients died. Conclusion:DIPS was efficacious, safe and reliable to that BCS patients. It rapidly reduced portal venous pressure, relieved liver congestion, and restored liver morphology and liver function in these patients.
ABSTRACT
Objective To study whether portal vein thrombosis can be prevented by partial splenectomy combined with portoazygos devascularization,by preserving the integrity of the blood flow of the inferior splenic vessels.Methods 156 patients with portal hypertension and megalosplenia were divided into two groups.62 patients in group A who underwent partial splenectomy and 94 patients in group B who underwent total splenectomy.The postoperative complications,levels of WBC and PLT,volumes of residual spleen,hepatic vein pressure gradient (HVPG),and prevalence of portal vein thrombosis between the two groups were compared.Results The surgery time of group A was slightly higher than group B [(189.0± 38.5) vs.(128.0±36.3) min,P＜0.05].The blood loss of group A was slightly higher than that of group B [(328.0±68.9) vs.(294.0±49.1) ml,P＜0.05].The postoperative infection rate,change in HVPG and rehemorrhage rate between the two groups showed no significant differences (P＞0.05).The elevation in Leucocyte after operation of the two groups were the same,peaking on day 3.The platelet count of group A increased more gently than group B (2 weeks vs 1 week),and its peak was closer to the normal threshold (P＜0.05).The thrombosis rate of the portal vein system in group A was significantly lower than group B within 1 year (P＜0.01).The residual spleen did not enlarge after operation (P＞0.05).Conclusion Subtotal splenectomy combined with pericardial devascularization in patients with portal hypertension and megalosplenia preserved the blood flow of the subsplenic polar vessels and reduced the incidence of portal vein thrombosis.
ABSTRACT
Objective@#To analyze the recent postoperative and long-term postoperative complications of open-splenectomy and disconnection in patients with portal hypertension.@*Methods@#There were 1 118 cases with portal hypertension who underwent open splenectomy and azygoportal disconnection from April 2010 to September 2015 at Department of Surgery, People′s Liberation Army 302 Hospital. Retrospective case investigation and telephone follow-up were conducted in October 2016. All patients had history of upper gastrointestinal bleeding before operation. Short-term complications after surgery were recorded including secondary laparotomy of postoperative abdominal hemostasis, severe infection, intake disorders, liver insufficiency, postoperative portal vein thrombosis and perioperative mortality. Long-term data including postoperative upper gastrointestinal rebleeding, postoperative survival rate and incidence of postoperative malignancy were recorded, too. GraphPad Prism 5 software for data survival analysis and charting.@*Results@#Postoperative short-term complications in 1 118 patients included secondary laparotomy of postoperative abdominal hemostasis(1.8%, 21/1 118), severe infection(2.9%, 32/1 118), intake disorders(1.0%, 11/1 118), liver dysfunction (1.6%, 18/1 118), postoperative portal vein thrombosis(47.1%, 526/1 118)and perioperative mortality(0.5%, 5/1 118). After phone call following-up, 942 patients′ long-term data were completed including 1, 3, 5 years postoperative upper gastrointestinal rebleeding rate(4.4%, 12.1%, 17.2%), 1, 3, 5-year postoperative survival rate(97.0%, 93.5%, 90.3%); the incidence of postoperative malignant tumors in 1, 3 and 5 years were 1.7%, 4.4% and 6.2%.@*Conclusions@#Reasonable choosing of surgical indications and timing, proper performing the surgery process, effective conducting perioperative management of portal hypertension are directly related to the patient′s short-term prognosis after portal hypertension. Surgical intervention can reduce the rates of patients with upper gastrointestinal rebleeding, improve survival, and do not increase the incidence of malignant tumors.
ABSTRACT
Recently, there have been many developments and improvements in portal hypertension surgery, but there are still many controversies regarding the surgical indications, the timing of surgery, and the choice of surgical procedures. Minimally invasive laparoscopy and robotics are the leading direction for the development of surgical techniques for portal hypertension. Surgical selection procedures should be based on evidence-based, but guidelines should not be blindly followed. Surgical development needs to strengthen multidisciplinary cooperation, and surgical reform is the driving force for surgical development.
ABSTRACT
Objective To study the impact of splenectomy and pericardial devascularization on the occurrence and development of portal vein thrombosis and the liver function in patients with cirrhosis complicated by portal hypertension.Methods 29 patients with cirrhosis and portal hypertension who underwent splenectomy and pericardial devascularization in the 302 Hospital of PLA from December 2012 to June 2013 were retrospectively studied.The incidences of PVT before and after operation were monitored.The liver function was assessed using the Child-Pugh classification.Results 29 patients with cirrhosis and portal hypertension underwent splenectomy and pericardial devascularization.The incidences of PVT in the preoperative period,12 days,3 months,6 months after operation were 10.3％,89.7％,51.7％,24.1％,respectively.The Child-Pugh scores in the preoperative period,12 days,3 months,6 months after operation were (5.2 ± 0.4),(5.6 ± 0.7),(5.2 ± 0.7),(5.3 ± 0.7),respectively.Conclusions The incidences of postoperative PVT increased after operation,but it decreased on long-term follow-up after operation.The liver function did not change.
ABSTRACT
Objective To evaluate the efficacy of intraopèrative ultrasonography (IOUS) on primary and repeated hepatectomies for hepatocellular carcinoma (HCC).Methods 430 patients underwent 555 operations for HCC.New tumors detected by IOUS at the primary and repeated hepatectomies were retrospectively analyzed.The long-term outcomes were also studied.Results IOUS had the highest sensitivity in the routinely used imaging examinations.The detection rate by each imaging modality decreased slightly but uniformly at the second hepatectomy.IOUS detected 56 new tumors in 30 patients (7.1％) at the primary hepatectomy and 13 new tumors in 8 (7.3％) at the second.The average size of tumor detected was 8.7±3.8 and 9.0±5.2 mm at the primary and second resections,respectively.The preoperative surgical plan was changed due to the IOUS findings alone in 24 patients (5.6％) at the primary hepatectomy,and in 7 (6.4％) at the second.Although recurrence was frequent in patients with new tumors detected at the primary hepatectomy,long-term survival after appropriate treatment for recurrence was similar to those patients without new tumors detected.Conlusions Despite recent progress in imaging modalities,IOUS is still the most sensitive examination.The same degree of precaution is necessary to detect new tumors using IOUS in repeated hepatectomy.Patients with new tumors detected by IOUS are at high risk for recurrence so that regular check-up is important to improve patient survival.
